GPU computing for shallow water flow simulation based on finite volume schemes. Castro Díaz, M. J., Ortega-Acosta, S., de la Asunción, M., Mantas, J. M., & Gallardo, J. 339(2):165–184. abstract bibtex This article is a review of the work that we are carrying out to efficiently simulate shallow water flows. In this paper, we focus on the efficient implementation of path-conservative Roe type high-order finite volume schemes to simulate shallow flows that are supposed to be governed by the one-layer or two-layer shallow water systems, formulated under the form of a conservation law with source terms. The implementation of the scheme is carried out on Graphics Processing Units (GPUs), thus achieving a substantial improvement of the speedup with respect to normal CPUs. Finally, some numerical experiments are presented.
